Their set of beers is an intriguing one: a Table Beer, a Mild Ale, a Pale Ale, and IPA and two Stouts. Though the latter aren't quite what they appear.
Single Stout (SS) looks like it's really a Porter to me. It's about the same strength as contemporary London Porters. The terms Single Stout and Porter seem to have been used fairly interchangeably in Ireland. Guinness Porter was a little stronger at about 1060º.
Double Stout (DS) is a little bit weaker than the Guinness of the day, Which was around 1075º. I assume Guinness Extra Stout was the beer it was supposed to compete with.
It's intriguing that Cairnes IPA wasn't all that much stronger - just 0.75% ABV - than the Table Beer. By the 1890s Table Beer had pretty much disappeared in England. With the dramatic fall in strength the conflict entailed, I don't expect that it survived WW I.
I assume that the beer simply called Ale was a type of Mild Ale. Though it is quite strong for a base-level Mild. Oddly, it's their second-strongest beer, after Double Stout.
The IPA is pretty close to the classic 1065º gravity. Though a poor degree of attenuation leaves it just under 5.5% ABV. It's not clear is this was a Stock Ale. If it were, then the real FG would have been considerably lower.
